Mariner East Overview

$ 3 Billion project in Pennsylvania The takeaway solution for the Marcellus / Utica liquids Most efficient export and processing option for one of the most reliable

and abundant NGL resource play in the US

Connected to a World-Class Northeast NGL Hub and Chemical Processing facility at Marcus Hook Industrial Complex (former Sunoco Refinery).

Repurposed as an NGL hub to receive Marcellus/Utica shale natural gas liquids (NGLs) for distribution and further processing to access international, local and regional markets. Phased approach: Mariner East is scalable

– Project will be expanded as production/ consumption needs grow – Combined ME1, ME2 and ME2X = 745 MBbl./day and scalable.

Marcus Hook Industrial Complex 800 acre facility: Former Sunoco Refinery 5 Million Bbls/ NGL storage at ME2 completion, in addition to

underground granite caverns ~2MM Bbl. capacity. 5 MMBBL of aboveground storage for crude oil and products 4 docks with deep water draft accommodating fully laden VLGC’s

Ample utilities available for power, air, steam, flare, fuel and water

systems for development of Olefin and Polyolefin processing. Rail receipts for Butane, Propane and Natural Gasoline = 30MBbl./day - Additional rail on premises for olefins and polyolefin outbound - Room to build significant additional rail capacity Truck inbound/ outbound

Mariner East NGL Economic Advantages Distance from Marcellus / Utica – pipeline cost

Very competitive export cost vs. USGC alternative

No vessel delays due to port congestion and minimal weather delays.

World class export operation with 5 MM Bbls, storage, redundant refrigeration and dock capacity capable of loading VLGC’s at 25,000 Bbl./Hr. Access to obtain the international arbitrage

– Arb expected to widen as crude price increases and naphtha becomes more expensive relative to NGL’s.

Access to distribution for propane and butane in the premium NE

fuels markets (BTU’s & gasoline blending). 17

Marcus Hook Chemical Processing Advantages

More than an ideal NGL export location. MHIC provides utilities and operational expertise for manufacturing and distribution to local and regional markets for NGL’s, Olefins and Poly-Olefins.

300 miles from abundant, advantaged NGL supply and

proximate to large Northeast US polyolefin demand Manufacturing potential- PDH, BDH, Polyolefin production,

Alkylate. Experienced process operators. Ample rail car storage & switching and serviced by both
